(3,4) And they can bind to erythrocytes,simultaneously with immune factors, causing hemagglutination and anemia. (5)Of the 119 known dietary lectins, about half are panhemagglutinins, clumping allblood types. The remainder are blood-type specific.
Two of the four cells will contain one recombinant chromosome. In eukaryotic cells, crossing over can also occur during mitosis. Somatic cells (non-sex cells) undergo mitosis to produce two distinct cells with identical genetic material.
For example, a woman can carry a recessive gene on one of the X chromosomes unknowingly, and pass it on to a son, who will express the trait Therefore, half of the daughters have the gene and can pass it to the next generation. The other half do not have the gene and, therefore, cannot pass it on. Half of the sons do not have the gene and cannot pass it on. The other half of the sons have inherited the gene and will express the trait or disorder.
